In this study, the elements of successful staff development programmes were identified and used as a frame of reference to determine the effectiveness of such programmes in Indian secondary schools. The empirical study revealed the strengths and weaknesses of current programmes. The school based staff development model proposed here is based on principles grounded in research and makes optimal use of existing structures. Attention is given to the active role of the principal and management staff as consumers and producers of knowledge, while the commitment of teachers to renewal and change is also highlighted.
